It's called a tilde. Is is used as an accent mark and a separator like a dash -. The complete definition according to Wikipedia is here. http://en.wikipedia.org/wiki/Tilde

most people don't even use it for it's ~actual use~ lol see what I did there? it's kind of annoying but oh well. is that what you mean? because if so it's kind of just decoration i guess.

It's called Tilde and it is used to mean "approximately" or "about"
for example I could say "there were ~100 people at the party"
and it means "there were about 100 people at the party"

But I mainly know it because it opens the developer console in most video games. Especially games on steam or games using the Source Engine.
